Questions & Answers about Můj kamarád koupil chleba a mléko v obchodě.
Why is můj used instead of moje with kamarád?
Because kamarád is masculine singular. Czech possessive pronouns agree in gender, number, and case with the noun they modify. You use můj for masculine singular nouns in the nominative case, while moje is for feminine or plural nouns.
How does koupil differ from kupoval, and why is the perfective used here?
koupil is the past tense of the perfective verb koupit (“to buy” as a single, completed action). kupoval is the past tense of the imperfective verb kupovat (“to be buying” or “to buy repeatedly”). Since the sentence describes a one-time, completed purchase, Czech uses the perfective koupil.
Why is chleba used instead of chléb, and what is the partitive genitive?
The dictionary (nominative) form is chléb with a long é. After certain verbs—especially those expressing eating, drinking, buying an indefinite amount—Czech often uses the partitive genitive (“some/any of X”). The genitive of chléb is chleba (the vowel shortens), so koupil chleba literally means “he bought some bread.”
Why does mléko stay the same in this sentence?
